The truth is that we need both testers and users, so that we could improve and enhance the platform over time.
And in regards to the "catch", yes there is actually ONE, that is we do not offer support of any kind on the use of YottaSnap service. This means that
if you choose to write application based on the service, you will have to do it on your own and we will not help you in debugging your application.
Having said that, we do provide support on the platform issues, such as cases where the service is down, or the service is broken.
